Octopus Deploy Documentation


Last updated

When you use Octopus Deploy to deploy software to Windows or Linux servers, the Octopus Server communicates with Tentacles installed on those servers. The Tentacles perform the tasks necessary to deploy the software.

Windows Tentacles are a lightweight agent service and Linux Tentacles are a .NET Core application.

The Octopus Server and Tentacles communicate in either Listening or Polling mode.

In Listening mode, Tentacles listen for instructions from the Octopus Server. When the Octopus Server has a task for a Tentacle, it connects to the Tentacle.

In Polling mode, Tentacles periodically poll the Octopus Server to check for any tasks that need to be performed.
